This advance notice of proposed rulemaking seeks public comments to inform future Food Safety and Inspection Service (FSIS) regulations for the labeling of meat and poultry products made using animal cell culture technology.  The Federal Meat Inspection Act (FMIA; 21 USC 601 et seq.) and the Poultry Products Inspection Act (PPIA; 21 USC 451 et seq.) require that meat and poultry products be truthfully and accurately labeled and that their labels be pre-approved by FSIS (21 USC 607(d) and 457(c), respectively), prior to movement in commerce.  FSIS issues labeling regulations and reviews and approves meat and poultry product labels pursuant to these statutory labeling requirements.  Food products made using animal cell culture technology and derived from the cells of livestock subject to the FMIA (cattle, sheep, swine, goats, and fish of the order Siluriformes) or the PPIA (chickens, turkeys, ducks, geese, guineas, ratites, and squabs) are subject to the labeling (and other applicable) requirements of these Acts and the regulations issued thereunder.
